Calculate FBA profit before sourcing. Include all 2026 fees, storage, and PPC. Find minimum viable selling price. Free Amazon FBA calculator.
Most Amazon FBA failures happen before the product ships — because sellers do not run the numbers correctly. Forgotten fees like monthly storage, returns, and PPC advertising can flip a 30% margin product into a money loser. This calculator includes every real cost Amazon sellers face in 2026 so you know your true margin before ordering inventory.
Beyond fulfillment and referral fees: Monthly storage $0.78/cubic foot standard, $2.40 October-December peak, returns processing $2-5 per return, removal fees if product does not sell, PPC advertising budget 15-25% of revenue for new products, and inbound shipping to Amazon fulfillment centers.
Amazon FBA experts recommend: minimum 30% net margin after all fees, minimum 100% ROI on product cost (buy for $10, sell for $20+), minimum 1,000 monthly sales volume in the category, no single competitor with 100+ reviews in a new niche. Use our calculator to filter viable from non-viable products.
Experienced FBA sellers target 30%+ net margin after all Amazon fees and COGS, and 50-100%+ ROI on inventory investment. Under 20% net margin is risky — thin margins mean negative profits when PPC costs spike, returns increase, or Amazon changes fees.
FBA fees have two components: Referral fee 8-15% by category plus Fulfillment fee based on size and weight. Measure your product dimensions and weight, determine your size tier, look up 2026 fulfillment fee, add referral fee percentage. Our calculator does this automatically.
Yes but more competitive than 2020-2022. Successful 2026 FBA sellers focus on differentiated products, strong brand, private label with unique features, and efficient PPC. Generic commodity products with no differentiation are extremely difficult to profit from in 2026.
